i will start the review of this one... but before that sorry for
suggesting this a bit later but about using UNNEST as part of the
sintax?
FOR var IN UNNEST array_expr LOOP
END LOOP
i like this because:
1) is cleaner when array_expr is ARRAY[1,2,3]
2) is not legal now to use the unnest() function without a SELECT in
the context of a FOR loop (or am i missing something?)
3) the unnest() function does the same so seems intuitive what a
FOR-IN-UNNEST do
what i don't know if is this syntax could co-exist with the unnest() function?
